Without transceivers, how are the various different computer systems supposed to communicate with each other over the CANbus? I suppose we could have one central control, that manages everything else over dumb IO, but that's... well... dumb.
Right. I meant collider as a subset. All colliders are inherently particle accelerators, but some accelerators are merely accelerators, not colliders (and technically some don't even impact a fixed target except to dump the beam).
A "collider" already implies that there are two beams traveling in opposite directions, as opposed to an "accelerator" which impacts a fixed target. There's no reason to build two separate rings when you can operate both beams within the same ring.
Anecdotal evidence. Who do you think is most likely to post reviews online? People burned by a failed hard drive, of course. The lower the cost, the more people are going to buy it, and the more reports of failures we get.
Any statistics gained from online reviews are of exceedingly low value.
That has always made me curious. Since early on, ATI has claimed higher compute performance in every generation, and yet nVidia owns that market. Is OpenCL an inferior interface to CUDA? Did nVidia just get there first with CUDA? Are they buying the market with programming support? Is it just that the compute market runs Linux, an area where nVidia has been stellar and ATI has been awful?
No. That's called adaptive optics, and it only works for ground based telescopes. There's no way in hell you're going to be able to adjust the mirror for atmospheric distortions when you're flying past it at 8km/s.
The atmosphere has nothing to do with anything. Active optics exist to maintain the shape of a mirror to compensate for changing external stresses. Unless you're inside the atmosphere, the atmosphere cannot produce external stress on the mirror. Of course, if you are inside the atmosphere, you have bigger issues than worrying about good quality images.
A chip in the glass could be a fatal injury for a spy satellite as the article suggests was the intended use. Such telescopes use active optics to improve image quality;
Why? It's in microgravity and temperature controlled. There's not going to be any sort of variation during operation to make active optics worthwhile. It's certainly not going to be adaptive optics, because you're moving across the atmosphere too rapidly to have any hope of keeping up with localized distortions. The only reason I could see it being useful is it would allow for more lax manufacturing tolerances, since you could fine tune it once you hit orbit.
Any sensible infrastructure would either run directly off methane, or would produce hydrogen gas from methane. No one in their right mind is considering using electrolysis to generate hydrogen.
As has been mentioned, this isn't the TSA, but rather the union representing the TSA screeners. The union is only interested in what is good for the screeners, not the system, and obviously should anything happen, having an armed guard to protect them is in their interest. On the other hand, any kind of restructuring of the system that might result in fewer screeners is against their interests.
There are a lot of people with ideas. There are only a few with a proficient enough programming/engineering background to understand whether those ideas are remotely possible, or a wide eyed pipe dream.
It's not bad in Fortran, except that often people want to read the entire data file (of unknown length) into an array first instead of processing the input line-by-line.
Well to be fair, Fortran has some pretty funky built in file IO constructs, and if you're doing binary data, the entire array must be read in at once.
If the bot can figure out the captcha correctly even one percent of the time, then it no longer functions as a rate limiter. Without a proper limiter, they just keep retrying with no consequence until they hit something.
No it doesn't. Putting rate limiters and account lockouts in place limits the frequency in which information can be submitted for authentication. All a CAPTCHA does is increase the cost of a brute force attack.
That's simply not true. nVidia's high end graphics card costs $650, not $1000. Their $1000 Titan is an entirely different breed of card. It's a workstation class card, and on modern nVidia hardware, there is actually a real, physical difference. They have separate 32-bit and 64-bit shaders. The workstation cards get a big chunk of 64-bit shaders, while the gaming cards get largely 32-bit shaders, because games have no need for double precision computation. When you spend $1000 on a Titan, what you're actually getting is a binned K6000, minus the ECC memory, and tech support than comes with the professional card. It's for people who want to do professional work, but are willing to sacrifice a bit of reliability for a huge cost savings.
Smarter reactor designs, yes, but we have no large scale commercial breeder reactors in operation. Even in breeder reactors, you can only run so far before transuranic elements taint the fuel and prevent breeding, and you have to reprocess it to use the remainder. Every time you restart, you need some amount of fissile material to kick off the reaction, although I suppose you could use a particle accelerator instead.
Well... the bit we care about will only be around 0.7% remaining, which is coincidentally its abundance among natural uranium found in the mantle, but who's counting.

The laws of physics say otherwise. Kinetic energy weapons are far more effective than lasers within the limits of their range.
No. That's called adaptive optics, and it only works for ground based telescopes. There's no way in hell you're going to be able to adjust the mirror for atmospheric distortions when you're flying past it at 8km/s.
To be fair, an ARM based system worth running a server on has taken a very long time to arrive.
I don't think the percentage of the market willing to crack open a Kindle to replace the battery is large enough to bother considering in forecasting.

It's called "combined heat and power". You bypass the inefficiencies of a generator and motor by using the thermal energy of the power plant directly.

So set up mobile conveyance. Put your conveyors on wheels, and reposition them as needed.
Large belted conveyor?

What are you even talking about? Power plants with "binary"?

When it's used to protect against brute force password attacks, a captcha is definitely a security mechanism.
Rate limiting protects against brute force password attacks, not CAPTCHAs.
No it doesn't. Putting rate limiters and account lockouts in place limits the frequency in which information can be submitted for authentication. All a CAPTCHA does is increase the cost of a brute force attack.
